:I have included the most relevant part of the output of
:"smartctl -d sat -a /dev/da0" below:
:

That's all normal except the Load_Cycle_Count is excessive. But
the Load_Cycle_Count is somewhat dependent on the manufacturer
and I don't see any errors reported in the output.
Another thing you can do is run 'hammer -f <device> show | less -B'
and search for lines beginning with the character 'B'. You would
type slash-carrot-B into LESS. The hammer show command checks
for problems.
